Hi Marc,
Glad you brought it up. Pesach I mean,

because this is where it is plainly taught in Torah that the goyim are allowed to participate fully if they become circumcised. Obeying Torah was NEVER optional. Everyone within the borders of Israel and then Judea were required to follow its statutes. No exceptions.
Prior to the antiGoyim knee-jerk of our people (except in the case of nephilim) brought about in the wake of the Babylonina captivity and the Greek invasion, those wishing to draw near could simply draw near. There were limits, but no hoops. Certainly nothing in Torah. If they wished to actually participate in Temple and the sacrificial system, they needed to be circumcised first. OK, that's a hoop, but it isn't ours, its His. But the choice to join His covenant and to join Israel was the goy's and NOT the Jew's. EVER! The goyim learned as they went along, which is pretty much what the Jerusalem council was saying in Acts. The goyim were to be viewed as little children that needed their teachers, not as dogs or lepers.
The
Master spoke on this very topic in Mat 23:
1 Then Yeshua addressed the crowds and his talmidim: Here we have the intended audience. Very important to context because He addressed not just His followers, but ALL that gathered. History tells us that there was no shortage of goyim in Jerusalem and Judea in those days. So you cannot claim that He only intended this instruction for Jews...
2 The Torah-teachers and the Prushim, he said, sit in the seat of Moshe. 3 So whatever they tell you, take care to do it. But dont do what they do, because they talk but dont act! 4 They tie heavy loads onto peoples shoulders but wont lift a finger to help carry them. ...and this is one of the many places that He addresses the 'customs' instituted by the Jewish leadership....
5 Everything they do is done to be seen by others; for they make their tfillin broad and their tzitziyot long, 6 they love the place of honor at banquets and the best seats in the synagogues, 7 and they love being greeted deferentially in the marketplaces and being called Rabbi....then comes His instruction concerning these customs...
8 But you are not to let yourselves be called Rabbi; because you have one Rabbi, and you are all each others brothers. 9 And do not call anyone on earth Father. because you have one Father, and he is in heaven. 10 Nor are you to let yourselves be called leaders, because you have one Leader, and he is the Messiah! 11 The greatest among you must be your servant, 12 for whoever promotes himself will be humbled, and whoever humbles himself will be promoted....the nature of this service is critical to understanding His message and the curse for ignoring this message is definitive and unambiguous...
13 But woe to you hypocritical Torah-teachers and Prushim! For you are shutting the Kingdom of Heaven in peoples faces, neither entering yourselves nor allowing those who wish to enter to do so. 14 [a]...above, Y'shua gives example of the nature of their offence. Below He deliniates the results of their teachings and their actions...
15 Woe to you hypocritical Torah-teachers and Prushim! You go about over land and sea to make one proselyte; and when you succeed, you make him twice as fit for Gei-Hinnom as you are!
Did you get that? In Torah, the children of Israel are given a ministry. It is to be priests to the goyim (excepting the nephilim, of course), but according to Him the "hypocritical Torah-teachers and Prushim" not only dropped the ball,
they hid it!

He states plainly that because of this behavior, they are only fit for the trash piles of the valley of Hinnom; where worms and fire consume rancid meat and trash and a stench rises continually. I cannot imagine stronger or more critical terms when considering the culture of the "
hypocritical Torah-teachers and Prushim" of 1st century Judea.
Poor Sha'ul, was so misunderstood for all the hyperbole he used in his method of teaching. All he was trying to get across was this: If you don't circumcise your heart to the Lord, a circumcision of the flesh would be worthless. He would be able to see their heart sooner than anyone could see their junk. He made the same point about Jews too. But he added that this in no way diminished the Torah command. His exact words were, "
God forbid!" When asked directly Sha'ul denied he EVER taught against Torah.
So here we arrive at the 'custom' of the court of the goyim (an innovation of the "
hypocritical Torah-teachers and Prushim"). Is it a good place to be? Depends on
Who you ask, know what I mean?
